Hi! you are asking about the children of Ida Duncan and Clarence Twyman, I have the following before Ida remarried to Clarence Ambrose Judd
Lewis H. Twyman 12/30/1897-12/31/1945 Hiawatha Cemetery, Opha May Twyman 11/7/1898-8/1/1951 Body donated to Science. Gladys A. Twyman 12/25/1903-1/30/1953 Mt. Saint Marys Cemetery, Kansas City, MO, Leo Twyman 1907-1957, Roy Twyman 1909-1987, Susan Prycila Twyman 9/3/1915 - 12/10/1918 (death Cert), Helen M. Twyman 9/12/1917 D 12/10/1918 (death cert)
I hope this information helps. Do you have any info at all on any other Duncan family members, like Ida's grandfather Thomas Duncan who married Sarah Jane Wison?
thanks
Mary
